Long string constants trigger Java StackOverflowError

[PaulStoffregen]

Very long string constants cause a Java exception. Tested on Linux 64 bit.

Here is a sample program which demonstrates the problem.

Same problem exists in version 1.0.5 on Windows 7 64 Bit

We're testing a new preprocessor and it compiles your sketch just fine.

New preprocessor tracked at #2636. Builds for testing it are available
